Returning Capacity on Demand resources
To return Trial Capacity on Demand (CoD) processor cores or memory, you must remove the processor cores or memory from the logical partitions to which they are assigned, thus making them available to be reclaimed by the server.
You do not need to remove the processor cores or memory from the same logical partitions to which they were assigned when you started your Elastic CoD request or Trial CoD. You can remove the processor cores or memory from any of your logical partitions.
